Sensation weighting in duration discrimination: A univariate, multivariate, and varied-design study of presentation-order effects.
Hellström Å, Patching GR, Rammsayer TH. Hellström Å, et al. Atten Percept Psychophys. 2020 Aug;82(6):3196-3220. doi: 10.3758/s13414-020-01999-z. Atten Percept Psychophys. 2020. PMID: 32342344 Free PMC article.
Stimulus discriminability is often assessed by comparisons of two successive stimuli: a fixed standard (St) and a varied comparison stimulus (Co). Hellstrom's sensation weighting (SW) model describes the subjective difference between St and Co as a dif …

Sensation weighting in comparison and discrimination of heaviness.
Hellström A. Hellström A. J Exp Psychol Hum Percept Perform. 2000 Feb;26(1):6-17. doi: 10.1037//0096-1523.26.1.6. J Exp Psychol Hum Percept Perform. 2000. PMID: 10696602
The standard weight (St) was 100, 200, or 300 g, either roving or fixed within a block. For each St, there were 5 comparison (Co) weights. The lifting orders were St-Co and, with 6 categories, Co-St. Time-order errors were negatively related to St magnitude, particularly w …

Time- and space-order effects in timed discrimination of brightness and size of paired visual stimuli.
Patching GR, Englund MP, Hellström A. Patching GR, et al. Among authors: hellstrom a. J Exp Psychol Hum Percept Perform. 2012 Aug;38(4):915-40. doi: 10.1037/a0027593. Epub 2012 Apr 2. J Exp Psychol Hum Percept Perform. 2012. PMID: 22468722
Despite the importance of both response probability and response time for testing models of choice, there is a dearth of chronometric studies examining systematic asymmetries that occur over time- and space-orders in the method of paired comparisons. ...The findings includ …

Presentation-order effects for aesthetic stimulus preference.
Englund MP, Hellström Å. Englund MP, et al. Among authors: hellstrom a. Atten Percept Psychophys. 2012 Oct;74(7):1499-511. doi: 10.3758/s13414-012-0333-9. Atten Percept Psychophys. 2012. PMID: 22760928
The results were well described by the SW model, which provided a better fit than did two extended versions of the Bradley-Terry-Luce model. ...In terms of the SW model, the valence-level-dependent TOEs can be explained as a consequence of differential stimulus weig …

Beware how you compare: comparison direction dictates stimulus-valence-modulated presentation-order effects in preference judgment.
Englund MP, Hellström Å. Englund MP, et al. Among authors: hellstrom a. Atten Percept Psychophys. 2013 Jul;75(5):1001-11. doi: 10.3758/s13414-013-0453-x. Atten Percept Psychophys. 2013. PMID: 23592182
Englund and Hellstrom (Journal of Behavioral Decision Making 25:82-94, 2012a) found a tendency to prefer the left (first-read) of two attractive alternatives but the right (second-read) of two unattractive alternatives-a valence-dependent word-order effect (W …

Intramodal and crossmodal pairing and anchoring in comparisons of successive stimuli.
Hellström Å, Cederström C. Hellström Å, et al. Atten Percept Psychophys. 2014 May;76(4):1197-211. doi: 10.3758/s13414-014-0635-1. Atten Percept Psychophys. 2014. PMID: 24604542 Clinical Trial.
Variation in TOEs across conditions was well accounted for by changes in parameters (stimulus weights, reference levels) in an extended version of Hellstrom's sensation weighting (SW) model. With an ISI of 2,000 ms, the first stimulus had a lower weight (less impact …

Time-order errors and standard-position effects in duration discrimination: An experimental study and an analysis by the sensation-weighting model.
Hellström Å, Rammsayer TH. Hellström Å, et al. Atten Percept Psychophys. 2015 Oct;77(7):2409-23. doi: 10.3758/s13414-015-0946-x. Atten Percept Psychophys. 2015. PMID: 26082151 Free article.
In the present study, we investigated how these two effects vary across interval types and standard durations, using Hellstrom's sensation-weighting model to describe the results and relate them to stimulus comparison mechanisms. ...The interstimulus interval was 900 ms. T …
